Description

hadoop dfs -mkdir /user//bar creates a directory "/user//bar" and you cant deleted /user/* as -rmr expands the glob

$ hadoop dfs -mkdir /user/rajive/a/*/foo
$ hadoop dfs -ls /user/rajive/a
Found 4 items
/user/rajive/a/* <dir> 2008-04-04 16:09 rwx------ rajive users
/user/rajive/a/b <dir> 2008-04-04 16:08 rwx------ rajive users
/user/rajive/a/c <dir> 2008-04-04 16:08 rwx------ rajive users
/user/rajive/a/d <dir> 2008-04-04 16:08 rwx------ rajive users

$ hadoop dfs -ls /user/rajive/a/*
/user/rajive/a/*/foo <dir> 2008-04-04 16:09 rwx------ rajive users

$ hadoop dfs -rmr /user/rajive/a/*
